If James rolls the number cube 250 times, predict the number of times it will land on an odd number

The correct answer is 125 times.

Step-by-step explanation:

Let's recall the formula of the probability:

Probability = Number of favorable outcomes/Total number of possible outcomes, therefore:

Probability of rolling a number cube and landing on an odd number = 3/6 = 1/2 because 1, 3 and 5 are the odd numbers out of 6 in a number cube.

It means that if we roll the cube, we have 50% of probability of landing on an odd number, in consequence:

If we roll the number cube 250 times, the number of times it will land an odd number is:

250 * 50% = 250 * 0.5 = 125

The correct answer is 125 times.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
